Inventor: DELAPENA JOHN MICHAEL DEVEREUX
IPC: D06F34/30
Filed: 1962-12-05
Abstract: 983,525. Washing machines. PORLESTER Ltd. Dec. 2, 1963 [Dec. 5, 1962], No. 46009/62. Heading A4F. [Also in Division D1] A washing machine has a control system comprising in circuit:- electrically controlled means for actuating the inlet and outlet valves, switch means adapted to detect the level of water in the tank, a thermostat responsive to temperature within the machine in circuit with a multi-portion switch which is automatically moved from one position to the next by electrical means. In operation water is admitted to the tank to a predetermined level when the heater 5 and pump H are brought into and remain in operation until the temperature reaches a predetermined value when the outlet valve is brought into operation and the water drains from the tank. A dish-washing machine comprises a cabinet A closed by a door B hinged at its lower edge, racks D for stacking the dishes and a spray tube E located between the racks. The inlet and outlet valves are controlled by solenoids 1 and 2 and the switch for detecting the water level is a pressure responsive double pole switch 3. The multiposition switch 7 is a rotary switch having five fixed contacts 7<SP>1</SP>-7<SP>5</SP>, a terminal 13 and a rotary contact 14 for connecting the terminal to each of the fixed contacts. The rotary contact is turnable with a ratchet wheel 26 having five peripheral indentations corresponding to the five positions of the switch, one indentation being engaged by a spring-biased pawl 28. Energization of a solenoid 8 having a movable core 39 connected to the pawl causes the core to move the pawl which moves back on de-energization of the solenoid 8 to move the ratchet wheel and thereby the rotary contact 14 to its next position. Similar multi-position rotary switches 9 and 10 are mounted on the same spindle as switch 7 and have rotary contacts 17 and 18 movable with contact 14. The rotary switch 7 is provided with an over-riding manual control. A double-pole microswitch 11 is provided which closes when the door B is closed and when electrical power is being supplied to the circuit an infra-red lamp 24 lights up. The machine is adapted to carry out a four-stage washing cycle. An electrical circuit is described and illustrated in Fig. 1.

Title: Process for removing monomers from an aqueous dispersion of a vinyl chloride homopolymer or copolymer
IPC: C08F6/16
Filed: 1975-11-06
Abstract: 1482061 Removing monomer from vinyl chloride polymer dispersions HOECHST AG 6 Nov 1975 [16 Nov 1974] 46049/75 Heading C3P A process for removing a monomer from an aqueous dispersion of a vinyl chloride polymer comprises: (a) admixing the aqueous dispersion of the polymer with a cationic, anionic or non- ionic surfactant, the surfactant being monomercompatible and being used in a proportion of 0À01-1% by weight based on the solid matter of the dispersion; (b) heating the dispersion to a temperature ranging from the freezing point of the polymer up to 120‹ C. and allowing the dispersion to remain at that temperature for 1 to 4 hours; and (c) continuously drawing off the gaseous matter issuing from the aqueous dispersion. The polymer may be polyvinyl chloride or vinyl chloride copolymers, e.g. copolymers of vinyl chloride with vinyl acetate, butadiene, butyl acrylate or methyl methacrylate. Suitable surfactants are (a) the alkali metal salts of fatty acids, the alkali metal or amine salts of fatty alcohol sulphates or sulphonates; (b) resinic soaps; (c) high molecular weight amine or quaternary ammonium salts; and (d) alkylarylpolyglycol ethers. The heating in step (b) may be effected directly by introducing steam into the dispersion and/or indirectly by means of an external heating source. The monomer is preferably expelled at atmospheric pressure and within the same temperature range as specified in step (b). In the specific examples an aqueous polyvinyl chloride suspension is mixed with sodium lauryl sulphate. After 4 hours the residual monomer content is 0 or 2 p.p.m.

Title: Optical record read apparatus
IPC: G11B7/1356
Filed: 1975-11-10
Abstract: 1532247 Reading records photo-electrically PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Nov 1975 [13 Nov 1974] 46373/75 Heading G1A An optical system for reading information on a carrier 1, Fig. 1, has a single radiation source 7 from which a read beam 21 and a focus beam 22 are derived by an element 8. The beams are  reflected from the carrier and pass via the element to a read detector 14 or focus detectors 17, 18. If the carrier moves from the desired plane the light spots formed on the detectors by the beams will expand; to make it possible for focusing signals to be derived a knife edge is placed at 23 so that the focusing beam is asymmetric and expands on to one of detectors 17, 18 while contracting on the other. The element 8 in Fig. 1 is a Woolaston prism, detailed in Fig. 5 (not shown); the prism also acts as a beam-splitter for the reflected beams, with a 45 degrees polarizer 12, though a separate splitter can be used. The prism splits the light from source 7 in such a way that beams 21, 22, both of which would fill the aperture of lens 13 in the absence of the knife edge, appear to come from different sources, Fig. 2 (not shown). As a result the knife edge can be positioned to primarily affect only the virtual source for the focus beam; thus the knife edge makes the focus beam asymmetric without reducing read beam size. In Fig. 3 the spots Si and Sf formed on the detectors are shown; in Fig. 3a the system in focus, whereas in 3b and 3c it is out of focus (in opposite senses). Focusing is indicated by the difference of the signals produced at 17 and 18, while the information on the carrier comes from the modulation at 14. If detector 14 is formed in two parts the difference of the signals they produce will indicate, in conjunction with the difference of the signals from 17 and 18, whether the prism is correctly placed relative to the detectors. The prism may be replaced by a diffraction grating, the two first order diffracted beams serving as the read and focus beams; separation of the reflected beams would then require a semitransparent mirror, but no 45 degrees polarizer.
